Application file 1 September 12, 1910, Serial No. 581,550. Renewed May6. 1912. Serial No. 695,570.

To all whom, it may canoe/22 lie it known that I, ()mvim Commune, acitizen of the United States of America, and a resident of Chicago,county of Cook, State of Illinois, have invented certain new and usefulIn'iprovements in Rimming-Winchines, of which the following is aSPQClfiCiIlZlUIl.

The main objects of this invention are to provide improved mechanism forshaping the edges of pie crust so as to form an upstanding rim thereoncapable of retaining soft material when the crust is filled to a depthgreater than that of the tins; and to provide improved means forpreventing the pie crust from adhering to the form after the rim iscompleted.

A specific construction embodying this invention is illustrated in theaccon'ipanying drawing, which is an enlarged sectional dctail of thoseparts of a pie crust rimming machine to which the present inventionrelates.

In the construction shown in the drawings, the pie tin 1 is carried by asupport 2 mounted at the upper end of an upright 3, which is arranged tomove vertically in the supporting frame of the machine so as to carrythe pie tin and its contents into and out of engagement with the rimforming mechanism which is mounted above the support 2. The up and downmovement of the upright 8 is accomplished by means of a strap 4;, whichis secured to the lower end 5 of the upright 3, and passes over a pulley6 to operating mechanism, not shown. It will be understood that a pullon the strap t in the direction of the small arrow will lift the pie tinsupport, and when the strap 4 is released, the Weight of the supportwill cause it to descend.

A form 7, which shapes the upper face of the pie crust 8 on the tin 1,is rigidly secured to the lower end of a stationary shaft or stud 9. Journaled on the shaft 1) above the form 7, is a sleeve 10, which carriesa bevel gear 11 at its upper end, and which also has rigidly connectedtherewith an arm 12. There is a depending stud 13 at the outer end ofthe arm 12, and joiiirnaled on this stud is a rimming device in the formof a roller lt, which has a conically formed periphery for forming therim of the pie crust, and which also has a groove 15 arranged to receiveand confine the edge of the pic (in 1 when the support 2 is at the upperlimit of its movement. This limit is determined by the engagement oi theflange 16 oil the support 2 with the bottom of the roller 14L. In orderto prevent a tendency of the shaft 3 to tilt when forced up againsttheroller 14-, a second roller 17 is provided. This need not be conical andshould preterably be located el =ar oi the edge of the pie tin, asshown. The roller 17 is carried by an arm 12 and is geared similarly tothe roller 14.

The rimming roller 14- is caused to travel around the edge oi? the pietin by rotating the arm 12, such rotation being accomplished by thepinion 18, which meshes with the gear 11, and which may be driven by anysuitable form oi. power mechanism connected with the shaft '19. In orderto insure proper rotation of the roller 1 it has rigidly connectedtherewith a pinion 20, which meshes with a stationary gear 21 mounted onthe sleeve of the form 7 The seat in the support 2, which receives thepie tin 1, is slightly larger than the corresponding part of the pietin, so that the pie tin may have a small amount of lateral movement inthe seat, as may be seen from the space 22 in the drawing, and thebottom of the groove 15 in the roller 14; is of such diameter that whenit engages the edge of the tin, the tin will be crowded toward theopposite side of the form, as in the drawing, and its center will beslightly eccentric with respect to the axis oi. rotation of the arm 12.

As the roller 1 L travels around the edge of the tin, the latter will bekept continuously shifting, and will have what might be said to be agyratory i'uovement with respect to the form, although neither the tinnor the form rotates. This relative movement of the tin and the formcauses the sides of the crust to be rolled to a thickness equal to thespace between the form and the tin on the side adjacent to the rimmingroller '14, and will keep the form at all times free from the dough, andwhen the support 2 is lowered, the dough will descend with the tinwithoutadhcring to the form.

Although but one specific embodiment of this invention is herein shownand described, it will be understood that numerous details of theci'mstruction shown may be altered or omitted without departing from thespirit of this invention, as defined by the following claims.

I claim 1. In a pie crust rimming machine, the combination of means forsupporting a pie tin, means for forming the inner face of a pie crust onsuch tin, rimming means for forming the outer edge of the crust, andmechanism for rotating one of said means relative to another, said meansbeing shaped and located so that said rotation will cause the tin andinner forming means to have a gyratory movement relative to each other.

2. In a pie crust rimming machine, the combination of a support for thetin, a form mounted above said support and adaptedto engage the innerface of the crust on the tin, rimming means mounted to travel around theform in a path concentric with the form and adapted to engage the edgeof the tin and adapted to force it to a position eccentric with theform, whereby the tin will be given a gyratory shifting movement withrespect to the form, through the movement of said rimming means.

3. In a pie crust rimming machine, the combination of a support for thetin, a sta tionary form mounted above said support and adapted to engagethe inner face of the crust on the tin, rimming means mounted to travelaround the form in a path concentric with the form and adapted to engagethe edge of the tin and adapted to force it to a position eccentric withthe form, whereby the tin will be given a gyratory shifting movementwith respect to the form, through the movement of said rimming means.

In a device of the class described, the combination of means forsupporting a pie tin, inner crust forming means, and rimming means, oneof said means being adapted when in engagement with the tin to hold itin a position eccentric to said inner crust forming means whereby therotation of said one means relative to said inner crust forming meanswill produce a gyrato-ry move ment of the tin with respect to said innercrust forming means.
